Trait Implementations

impl Encoding for Hex

fn encode_to_slice(&self, src: &[u8], dst: &mut [u8]) -> Result<usize, Error>

Encode the given slice into the destination buffer.

fn encoded_len(&self, bytes: &[u8]) -> usize

Calculate the length of the given data after encoding.

fn decode_to_slice(&self, src: &[u8], dst: &mut [u8]) -> Result<usize, Error>

Decode hexadecimal (upper or lower case) with branchless / secret-independent logic

fn decoded_len(&self, bytes: &[u8]) -> Result<usize, Error>

Calculate the length of the given data after decoding.

fn encode<B: AsRef<[u8]>>(&self, bytes: B) -> Vec<u8>

Encode the given buffer, returning a Vec<u8>

fn encode_to_string<B: AsRef<[u8]>>(&self, bytes: B) -> Result<String, Error>

Encode the given slice to a String with this Encoding.

fn encode_to_writer<B, W>(
    &self,
    bytes: B,
    writer: &mut W
) -> Result<usize, Error> where
    B: AsRef<[u8]>,
    W: Write, 

Encode the given slice with this Encoding, writing the result to the supplied io::Write type, returning the number of bytes written or a Error.

fn encode_to_file<B, P>(&self, bytes: B, path: P) -> Result<File, Error> where
    B: AsRef<[u8]>,
    P: AsRef<Path>, 

Encode self and write it to a file at the given path, returning the resulting File or a Error.

fn decode<B: AsRef<[u8]>>(&self, encoded_bytes: B) -> Result<Vec<u8>, Error>

Decode the given buffer, returning a Vec<u8>

fn decode_from_str<S: AsRef<str>>(&self, encoded: S) -> Result<Vec<u8>, Error>

Decode the given string-alike type with this Encoding, returning the decoded value or a Error.

fn decode_from_reader<R: Read>(&self, reader: &mut R) -> Result<Vec<u8>, Error>

Decode the data read from the given io::Read type with this Encoding, returning the decoded value or a Error.

fn decode_from_file<P: AsRef<Path>>(&self, path: P) -> Result<Vec<u8>, Error>

Read a file at the given path, decoding the data it contains using the provided Encoding, returning the decoded value or a Error.

impl Debug for Hex

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq<Hex> for Hex

fn eq(&self, other: &Hex) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Hex) -> bool

This method tests for !=.

impl Eq for Hex

impl Ord for Hex

fn cmp(&self, other: &Hex) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialOrd<Hex> for Hex

fn partial_cmp(&self, other: &Hex) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Hex) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Hex) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Hex) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Hex) -> bool
